“How much will Power Apps cost?” usually comes with a second question: “How long will it take?” For most SMEs, getting something useful in front of the team quickly matters as much as the budget.
Power Apps is usually faster to deliver than traditional custom software, and much easier to change afterwards. This guide covers what drives the timeline and the cost, how licensing works, and where the comparison with custom development has real limits.
Licensing: You May Already Have Some Access
Many SMEs don’t realise that several Microsoft 365 plans already include limited Power Apps use rights. These include Microsoft 365 Business Basic, Business Standard and Business Premium, as well as E3, E5 and F3. They let you build and run apps that use standard connectors such as SharePoint, Teams, Outlook and Excel.
For a simple approval tool, an internal tracker or a basic data capture form built on SharePoint, you may not need any extra licensing at all.
The picture changes once an app needs any of the following:
- Microsoft Dataverse. Dataverse is Power Platform’s own database, and it counts as premium. Many apps that start out simple end up needing it as they grow, for stronger security, related data or larger volumes.
- Premium or custom connectors. Connecting to systems such as SQL Server, Salesforce or SAP, or to your own APIs through a custom connector, needs a premium licence.
- On-premises data. Reaching systems inside your own network through the on-premises data gateway is also premium.
For premium apps, the main options are Power Apps Premium, licensed per user, and the per app pay-as-you-go meter, billed through an Azure subscription. From 2 January 2026, Microsoft stopped selling the separate Power Apps per app licence to new customers through some purchasing routes, so whether you can still buy it depends on how you buy your Microsoft licences. Some Dynamics 365 licences also include Power Apps rights for apps that extend those Dynamics 365 applications.
Licensing is often the cost that surprises people most, so check what you already have before any build starts. As a Microsoft Solutions Partner, we check this as part of scoping.
Power Apps vs Traditional Development
| Traditional custom development | Power Apps | |
|---|---|---|
| Typical timeline | Usually longer, because the application is designed, coded and tested from scratch | In our experience, 2 to 4 weeks for simple apps, 2 to 4 months for complex apps and 4 to 8 months for large apps |
| Maintenance afterwards | Most changes need a developer and a new release | Trained business users can make many routine changes themselves |
| What it can deliver | Almost anything, given enough time and budget | Covers most forms, workflows, dashboards and mobile data capture. Specialist requirements may still need custom code |
| Path to a first version | Often one long build before launch | Core features can go live first, with more added in stages |
The third row matters most. Power Apps isn’t a universal replacement for custom development. For highly specialised technical requirements, complex algorithms or high-performance processing, custom development or a hybrid approach may still be the right choice. But most SMEs need forms, approvals, trackers, dashboards and mobile tools for staff working away from the office. For apps like these, Power Apps usually meets the need without a long traditional build.
What Drives the Timeline and the Cost
The same factors decide both how long a Power Apps project takes and what it costs.
App complexity. A single-screen form that writes to a SharePoint list is a very different project from a multi-screen app with complex business rules, offline use and integration with several other systems.
Data sources. Power Platform has more than 1,000 prebuilt connectors, which keeps common integrations quick. If a system has no prebuilt connector, you need a custom connector, which adds design and testing time.
Offline requirements. Apps that must work reliably without a connection need more careful design and testing. Field service teams, warehouse staff and site visits are typical examples.
Governance and security. A simple departmental tool needs less review than an app handling sensitive customer data across the whole organisation.
Licensing model. Whether the app can run on your existing Microsoft 365 rights or needs premium licences is often the biggest factor in ongoing cost. The data sources above usually decide this.
Who looks after it. Training an internal owner to maintain the app costs a little more upfront but reduces what you spend on changes later. Relying on a partner for every change does the opposite.
Realistic Timelines
These ranges reflect our own delivery experience. Your timeline will depend on the factors above and is confirmed once we’ve scoped the work.
2 to 4 weeks: Simple single-purpose apps, such as a basic approval workflow, a data capture form or an internal request tracker.
2 to 4 months: More complex apps with several screens, business rules and multiple data sources. Many genuinely useful business apps fall into this range.
4 to 8 months: Large apps with heavy customisation, complex offline needs or integration with several older systems that have no existing connector. At this point it’s worth asking whether the scope has outgrown a single build and should be split into phases.
Whatever the complexity, a phased approach usually works best. Get the core features working and in use quickly, then add more once people are using the app and can tell you what’s missing.
Where the Real Advantage Shows Up
The build is only part of the picture. The bigger advantage comes after launch.
With traditional custom development, every small change usually means going back to a developer and waiting for the next release. That might be a new column, an adjusted validation rule or an extra approval step. With Power Apps, a trained internal owner can make many of these changes without starting a new development project each time.
That advantage keeps paying off for as long as the app is in use, because the app keeps pace with how the business works.
When Power Apps Isn’t the Right Choice
Power Apps isn’t always the answer.
- If you need high-performance computing or complex algorithmic processing, custom development may serve you better.
- If your requirements are highly specialised and can’t be met through configuration, custom code may be unavoidable for parts of the solution.
- If nobody internally will own the app and keep improving it, you may end up waiting on someone else for every change anyway, just inside Power Apps rather than outside it.
Often the most practical answer is a hybrid: Power Apps for most of the need, with custom development kept for the parts that genuinely require it.
Your Next Step
If you have a manual process running on spreadsheets, email chains or paper, it’s worth a short conversation before assuming a long, traditional build is the only option.
